At least one of the components of the electronic device 101 may be omitted, or other components may be additionally included in the electronic device 101.

The bus 110 is a circuit that interconnects the aforementioned components of the electronic device 101 and transmits communication signals (e.g., control messages) between the components.

The processor 120 carries out operations or data processing related to control and/or communication of at least one other component (for example, the memory 130, the input/output interface 150, the display 160, or the communication interface 170) of the electronic device 101.

The memory 130 stores commands or data (e.g., a reference pattern or a reference touch area) associated with one or more other components of the electronic device 101. The memory 130 stores software and/or a program 140. For example, the program 140 includes a kernel 141, a middleware 143, an application programming interface (API) 145, an application program 147, with one or more of the kernel 141, the middleware 143, and the API 145 being referred to as an Operating System (OS).

The kernel 141 controls or manages system resources (e.g., the bus 110, the processor 120, or the memory 130) used for performing an operation or function implemented by the other programs (e.g., the middleware 143, the API 145, or the application program 147). Further, the kernel 141 provides an interface through which the middleware 143, the API 145, or the application program 147 may access the individual elements of the electronic device 101 to control or manage the system resources.

The middleware 143 functions as an intermediary for allowing the API 145 or the application program 147 to communicate with the kernel 141 to exchange data. In addition, the middleware 143 processes one or more task requests received from the application program 147 according to priorities thereof. For example, the middleware 143 assigns priorities for using the system resources (e.g., the bus 110, the processor 120, or the memory 130) of the electronic device 101, to at least one application of the application program 147. For example, the middleware 143 performs scheduling or loading balancing on the one or more task requests by processing the one or more task requests according to the priorities assigned thereto.

The API 145 is an interface through which the application 147 controls functions provided from the kernel 141 or the middleware 143, and may include at least one interface or function (e.g., instruction) for file control, window control, image processing, or text control.

The input/output interface 150 forwards instructions or data input from a user through an input/output device (e.g., various sensors, such as an acceleration sensor or a gyro sensor, and/or a device such as a keyboard or a touch screen), to the processor 120, the memory 130, or the communication interface 170 through the bus 110. For example, the input/output interface 150 provides the processor 120 with data on a user' touch entered on a touch screen. Further, the input/output interface 150 outputs instructions or data, received from the processor 120, the memory 130, or the communication interface 170 via the bus 110, through an output unit (e.g., a speaker or the display 160).

The display 160 includes, for example, a liquid crystal display (LCD), a light emitting diode (LED) display, an organic LED (OLED) display, a micro electro mechanical system (MEMS) display, an electronic paper display, etc. The display 160 displays various types of content (e.g., a text, images, videos, icons, symbols, etc.) for the user. The display 160 may include a touch screen and receive a touch input, a gesture input, a proximity input, a hovering input, etc., using an electronic pen or a user's body part. The display 160 may display a web page.

The server 106 may include a group of one or more servers.

According to the present disclosure, all or a part of operations performed in the electronic device 101 can be performed in another electronic device or multiple electronic devices (e.g., the first external electronic device 102 or the second external electronic device 104 or the server 106). In this case, when the electronic device 101 should perform some functions or services automatically or by a request, the electronic device 101 may make a request for performing at least some functions related to the functions or services by the first external electronic device 102, the second external electronic device 104, or the server 106, instead of performing the functions or services by itself. The first external electronic device 102, the second external electronic device 104, or the server 106 may perform a function requested from the electronic device 101 or an additional function and transfer the performed result to the electronic device 101. The electronic device 101 can provide the requested function or service to another electronic device by processing the received result as it is or additionally.

In FIG. 3A, a perspective view of the electronic device 300 is provided. In FIG. 3B, a front view of the electronic device 300 is provided. The electronic device 300, according to various embodiments, may be the same as electronic devices 101 and 201 illustrated in FIGS. 1 and 2 .

In FIGS. 3A and 3B at least a portion of a housing of the electronic device 400 forms at least a portion of an antenna. For example, at least one gap may be formed in a housing portion 310 of the electronic device 300. The housing portion 310 may form the whole or at least a portion of the exterior of the electronic device 300. The housing portion 310 may be formed of materials, such as a plastic, a metal, carbon fiber and other fiber composites, ceramics, glass, and wood, or combinations thereof.

The entire housing portion 310 may be formed of one material or a combination of materials, and may be partially formed of materials having different physical properties.

The housing portion 310 of the electronic device 300 may have a top face, a bottom face, and a plurality of side faces. The top face, the bottom face, and the plurality of side faces of the housing portion 310 may be formed of the same material, or of materials having different physical properties.

The housing portion 310 of the electronic device 300 may include a display 301 (the display 301 may be referred to as a “touch screen” when a touch panel is mounted) on the top face thereof.

A receiver 302 may be disposed above the display 301 so as to receive a voice of a counterpart. Components for conducting various functions of the electronic device 300 may be arranged around the receiver 302. The components may include one or more sensors 303, 304, and 305. The sensors 303, 304, and 305 may include at least one of an illuminance sensor (e.g., an optical sensor), a proximity sensor (e.g., an optical sensor), an infrared sensor, and an ultrasonic sensor. The front face of the housing portion 310 may additionally include at least one front camera 306.

The display 301 may be formed in a large size to occupy a greater portion of the top face of the electronic device 300. A main home screen refers to a first screen that is displayed on the display 301 when the power source of the electronic device 300 is turned on. When the electronic device 300 has several pages of different home screens, the main home screen may be the first home screen among the several pages of home screens. The home screen may display shortcut icons to execute frequently used applications, a main menu switching key, time, weather, or the like. The main menu switching key may cause the main screen to be displayed on the display 301. In the upper end of the display 301, status bars may be formed to indicate the statuses of the electronic device 300, such as a battery charge status, a received signal strength, and the current time. Below the display 301, a home key 307 a, a menu key 307 b, and a back key 307 c may be formed.

When the home key 307 a is pushed, the electronic device 300 may display the main home screen on the display 301. For example, when the home key 307 a is touched in the state where a home screen, which is different from the main home screen, or the menu screen is displayed on the display 301, the main home screen may be displayed on the display 301. In another example, when the home key 307 a is touched while applications are executed on the display 301, the main home screen may be displayed on the display 301. In another example, the home key 307 a may be used in order to cause the most recently used application or a task manager to be displayed on the display 301.

The menu button 307 b may provide a connection menu that may be used on the display 301. For example, the connection menu may include a widget addition menu, a background screen change menu, a retrieve menu, an edition menu, and an environment setting menu. The back button 307 c may cause the screen, which was executed just prior to the currently executed screen, to be displayed, or may cause the most recently used application to be terminated.

The housing portion 310 of the electronic device 300 may include a housing portion that includes a first face, a second face that faces opposite to the first face, and a first side face that encloses at least a portion of the space between the first and second faces. The housing portion 310 may include a conductive material and a non-conductive material.

The housing portion 310 may be a conductive member (e.g., a metallic member), and at least a portion of the front face, at least a portion of the rear face, or at least a portion of the side face may be formed as a conductive member.

Alternatively, the housing portion 310 may be a non-conductive member (e.g., a non-conductive housing), and at least a portion of the front face, at least a portion of the rear face, or at least a portion of the side face of the housing portion 310 may be formed as a non-conductive member.

For example, when the housing portion 310 of the electronic device 300 is a metallic housing, the metallic housing may include an exterior conductive member that forms the exterior of the metallic housing.

The exterior conductive member may include metal frames arranged along the rim of the electronic device 300. For example, the metal frame may be arranged to extend to at least a partial region of the rear face of the electronic device 300 in which the rim extends.

The conductive member may form at least a partial region of the rim of the electronic device 300, and the non-conductive member may form the remaining portion of the rim. In such a case, the housing may be formed in a manner in which the non-conductive member is formed on the conductive member through insert injection molding.

A conductive rim structure, which forms the rim of the housing of the electronic device 300, may include a plurality of conductive members 321 to 324. The conductive members 321 to 324 are metal frames that form at least a portion of the exterior, and because the electronic device 300 has a substantially rectangular shape in a plan view, the metal frames may include first to fourth metal frames. For example, the conductive members 321 to 324 may form a polygonal shape without being limited to the substantially rectangular shape, and may form a curved shape (e.g., a circular shape or an oval shape).

The housing portion 310 may include first to fourth sides. The first side and the second side, which are opposite to each other, may have the same length, the third side and the fourth side, which are opposite to each other, may have the same length, and the third and fourth sides may be configured to be longer than the first and second sides. Hereinafter, a conductive member will be referred to as a metal frame.

When viewing the electronic device 300 from the front side, the metal frame positioned at the top side of the housing of the electronic device 300 may be referred to as a first metal frame 321, the metal frame positioned at the bottom side of the housing of the electronic device 300 may be referred to as a second metal frame 322, the metal frame positioned at the left side of the housing of the electronic device 300 may be referred to as a third metal frame 323, and the metal frame positioned at the right side of the housing of the electronic device 300 may be referred to as a fourth metal frame 324.

The first metal frame 321 or the second metal frame 322 may include at least one non-conductive member. For example, the first metal frame 321 and the second metal frame 322 may include non-conductive members 331 and 332 and non-conductive members 333 and 334, respectively. Each of the non-conductive members 331, 332, 333, and 334 is made of an insulation material, and may thus be referred to as an insulation portion. Further, each of the non-conductive members 331, 332, 333, and 334 splits adjacent metal frames and may thus be referred to as a split portion.

The non-conductive members may be arranged in the first metal frame 321, in the second metal frame 322, or in both of the first metal frame 321 and the second metal frame 322. For example, a pair of non-conductive members 331 and 332 respectively disposed at the opposite ends of the first metal frame 321 may be defined as first non-conductive members, and a pair of non-conductive members 333 and 334 respectively disposed at the opposite ends of the second metal frame 322 may be defined as second non-conductive members.

At least a portion of a metal frame split by at least one non-conductive member may operate as at least a portion of an antenna radiator. For example, at least a portion of each of the metal frames 321 to 324 split by the first non-conductive members 331 and 332 and the second non-conductive members 333 and 334 may be used as an antenna radiator. For example, the first metal frame 321 may be a top center radiator that is provided by a pair of first non-conductive members 331 and 332 formed at a predetermined interval, and the second metal frame 332 may be a bottom center radiator that is provided by a pair of second non-conductive members 333 and 334 formed at a predetermined interval. At least one of the first non-conductive members 331 and 332 or the second non-conductive members 333 and 334 may be formed when a non-conductive member is formed on a metal frame through insert injection molding.

When one of the first metal frame 321 and the second metal frame 322 is fed with power to operate as at least a portion of an antenna radiator, one of the third metal frame 323 and the fourth metal frame 324 is electrically coupled to at least one of the first metal frame 321 and the second metal frame 322 to operate as at least a portion of an antenna radiator.

The pair of first non-conductive members 331 and 332 may be formed by at least partially filling one or more gaps between the metal frames with a non-conductive material. The pair of second non-conductive members 333 and 334 may be formed by filling a gap between the metal frames with a non-conductive material. The first non-conductive members 331 and 332 and the second non-conductive members 333 and 334 may be arranged to be vertically symmetric or asymmetric and/or horizontally symmetric or asymmetric with reference to the display.

The first metal frame 321 may further include top side metal frames 323 a and 324 a that respectively extend from the third and fourth metal frames 323 and 324, and are then bent. For example, the first non-conductive members 331 and 332 may be arranged between the first metal frame 321 and the top side metal frames 323 a and 324 a, respectively. The first metal frame 321 may operate as an antenna radiator that is fed with power from a power feeding circuit so as to form resonance. When the first metal frame 321 is fed with power from the power feeding circuit to operate as an antenna radiator, at least a portion of the top side metal frame 323 a and the third metal frame 323 and at least a portion of the top side metal frame 324 a and the fourth metal frame 324 are electrically coupled to each other so as to operate as a portion of the antenna radiator.

The second metal frame 322 may further include bottom side metal frames 323 b and 324 b that respectively extend from the third and fourth metal frames 323 and 324, and are then bent. For example, the bottom side metal frames 323 b and 324 b may be formed by extending from the third and fourth frames 323 and 324, respectively, and being bent at a right angle. The second non-conductive members 333 and 334 may be arranged between the second metal frame 322 and the bottom side metal frames 323 b and 324 b, respectively. The second metal frame 322 may operate as an antenna radiator that is fed with power from a power feeding circuit so as to form resonance. When the second metal frame 322 is fed with power from the power feeding circuit to operate as an antenna radiator, at least a portion of the bottom side metal frame 323 b and the third metal frame 323 and at least a portion of the bottom side metal frame 324 b and the fourth metal frame 324 are electrically coupled to each other so as to operate as a portion of the antenna radiator.

At least some of various electronic components may be arranged on the first metal frame 321 of the electronic device 300. For example, in the first metal frame 321, at least one of a socket device for inserting a card-type external device or a memory card for expanding a storage space may be accommodated. An earphone jack connector configured to connect an earphone jack may be disposed on the first metal frame 321. However, the arrangement of the socket device or the memory card is not limited thereto.

On the second metal frame 322, an interface connector port 308 may be disposed in order to perform a transmission/reception function by an external device as well as to charge the electronic device 300 by receiving power applied from an external power source. For example, an earphone jack hole may be disposed at one side of the interface connector port 308. However, without being limited thereto, at least one of the above-mentioned electronic components may be disposed outside the metal frame.

At least one side key button may be disposed on the third metal frame 323 to perform a volume up/down function, a scroll function, etc.

At least one second side key button 309 may be disposed on the fourth metal frame 324. The second side key buttons 309 may serve to perform a power ON/OFF function, an electronic device wake-up/sleep function, etc.

At least one key button may be disposed in at least a partial region, other than the display 301, in the front face of the electronic device 300. The key button may perform a home key button function. A fingerprint recognition sensor device may be disposed on the top surface of the home key button. The home key button may be configured to perform a first function (e.g., the home screen return function or the wake-up/sleep function) by an operation of physically pressing the home key button, and to perform a second function (e.g., a fingerprint recognition function) by an operation of swiping the top surface of the home key button.

The display 301 of the electronic device 300 may be configured to have a flat surface or a curved surface at one side or at each side. The display may include a curved face portion having a curvature. The curved face portion may extend along an edge region of the display and along the X axis and/or the Y axis. The electronic device 300 may selectively display at least a portion of information by controlling a display module.

FIGS. 3C to 3E illustrate configurations of an antenna provided in a metal frame of an electronic device, according to various embodiments of the present disclosure.

Referring to FIG. 3C, the electronic device 300 is shown. The first metal frame 321 (i.e., a conductive member) disposed on the housing portion 310 of the electronic device 300, according to various embodiments, may operate as at least a portion of an antenna radiator that is fed with power from the communication circuit 380 so as to form resonance. For example, at least one of the metal frames 321; 323, 323 a; 324, 324 a, which are respectively split by the non-conductive members 331 and 332, may operate as at least a portion of an antenna radiator. For example, the first metal frame 321 may operate as at least a portion of a main antenna radiator, and each of the side metal frames 323 and 323 a disposed at one side of the first metal frame 321 and/or the side metal frames 324 and 324 a disposed at the other side of the first metal frame 321 may operate as at least a portion of an auxiliary antenna radiator by each being electrically coupled to the first metal frame 321. Each of the side metal frames 323, 323 a; 324, 324 a may be referred to as a coupling antenna or a coupling radiator.

The first metal frame 321 may be fed with power by a power feeding unit 390 disposed on a circuit board so as to operate as at least a portion of an antenna radiator. In such a case, the conductive member 321 may serve as a main antenna of the electronic device 300. The other conductive members 323 and 324, in the vicinity of the conductive member 321, may not be electrically connected to the communication circuit 380.

As another example, the other conductive members 323 and 324 in the vicinity of the conductive member 321 may be electrically connected to each of the ground members 371 and 372 of the circuit board 370 or other ground members 373 and 374. Each of the ground members 371 to 374 may be formed as a ground plane in at least a partial region of the circuit board 370.

The communication circuit 380 may be formed in at least a portion of the circuit board 370, which exists within the electronic device 300. The circuit board 370 may generally refer to all the boards that may be conventionally mounted within the electronic device 300 (such as a printed circuit board (PCB), a flexible printed circuit board (FPCB), and printed board assembly (PBA)).

The electronic device 300 may differently adjust the length of an antenna depending on a bandwidth to be supported. For example, the antenna bandwidth may be differently adjusted depending on the position of a non-conductive member, the position of a power feeding unit, an opening (i.e., a gap or split portion), and a ground unit.

At least one antenna may be formed in the electronic device 300 by using a metal frame. The antenna may be configured by using a single band antenna structure and/or a multi-band antenna structure. An ordinary antenna used in a portable electronic device has a planar inverted-F antenna (PIFA) or monopole radiator as a basic structure, and the number of the antennas may be determined depending on a service frequency, a service bandwidth, and a kind of the service. Although frequencies are different depending on the region of the world, typically a low band of 700 MHz to 900 MHz, a mid-band of 1700 MHz to 2100 MHz, and a high band of 2300 MHz to 2700 MHz are used as major communication bands, and various wireless communication services, such as BT, GPS, and WIFI may be additionally used. Service bands, which are similar to each other in terms of frequency bands, are lumped with each other and are designed to be split to several antennas.

For example, a main antenna, which is in charge of voice/data communication (e.g., GPRS, WCDMA, or LTE), which is the principal communication of an electronic device, is positioned in a lower end of the electronic device where the number of metal components that undermine an antenna performance is small, and in view of European standards, the following bands should be implemented: 24 bands in total should be implemented including 2G (GSM850, EGSM, DCS, PCS), WCDMA (B1, B2, B5, B8), and LTE (B1, B2, B3, B4, B5, B7, B8, B12, B17, B18, B19, B20, B26, B38, B39, B40, B41).

The electronic device 300 may lump service bands, of which the frequency bands are similar to each other over at least two regions, with each other so as to implement antennas. As an example, 2G (GSM850, EGSM, DCS, PCS), WCDMA (B1, B2, B5, B8) and LTE (B1, B2, B3, B4, B5, B8, B12, B17, B18, B19, B20, B26, B39) may be implemented in Main 1 antenna, and an antenna for LTE (B7, B38, B40, B41) may be designed in Main 2 antenna.

Referring to FIG. 3D, an electronic device 3100 is shown. The electronic device 3100 may be the same as the electronic device 101 of FIG. 1 .

The electronic device 3100, according to various embodiments, may include at least one gap in a side face, and a non-conductive member that fills at least a portion of the at least one gap. For example, the electronic device 3100 may include non-conductive members 3133 and 3134, which are respectively disposed in at least partial regions of third and fourth metal frames 3123 and 3124, which are located at opposite sides of the housing portion, respectively.

The first and second non-conductive members 331 and 332, illustrated in FIG. 3C, are disposed in the metal frames that are disposed in the upper end, lower end, or upper and lower ends of the housing portion of the electronic device, and the first and second non-conductive members 3133 and 3134, illustrated in FIG. 3D, are disposed on side faces of the housing portion of the electronic device 3100, and may include, for example, a first non-conductive member 3133 disposed on the first side face and a second non-conductive member 3134 disposed on the second side face.

The metal frame 3121 disposed around the upper end of the electronic device 3100 may operate as at least a portion of an antenna radiator by being fed with power from the communication circuit 3180. For example, each of the metal frames 3121, 3123, and 3124, which are respectively split by the non-conductive members 3133 and 3134, may operate as at least a portion of an antenna radiator. The first metal frame 3121 may operate as a main antenna radiator, and the first side metal frame 3123 disposed at one side of the first metal frame 3121 and/or the side metal frame 3124 disposed at the other side of the first metal frame 3121 may operate as an auxiliary antenna radiator by being electrically coupled to the first metal frame 3121. At least one side metal frame 3123 or 3124 may be referred to as a coupling antenna or a coupling radiator.

The first metal frame 3121 is fed with power by the power feeding unit 3190 formed on the circuit board 3170 to operate as a main antenna radiator such that the first metal frame 3121 may serve as the main antenna of the electronic device 3100. The other conductive members 3123 and 3124 in the vicinity of the conductive member 3121 may be or may not be electrically connected to the communication circuit 3180.

As another example, the other conductive members 3123 and 3124 in the vicinity of the first metal frame 3121 may be electrically connected to each of the ground members 3172 and 3173 of the circuit board 3170. Each of the ground members 3172 and 3171 may be formed as a ground plane in at least a partial region of the circuit board 3170.

The communication circuit 3180 may be formed in at least a portion of the circuit board 3170, which exists within the electronic device 3100. The circuit board 3170 may generally refer to all the boards that may be conventionally mounted within the electronic device 3100, such as a PCB, a FPCB, and PBA.

The electronic device 3100 may differently adjust the length of an antenna depending on a bandwidth to be supported. For example, the antenna bandwidth may be differently adjusted depending on the distance between a power feeding unit and a ground unit.

Referring to FIG. 3E, an electronic device 3200 is shown. The electronic device 3200 may be the same as the electronic device 101 of FIG. 1 .

The electronic device 3200, according to various embodiments, may include an additional ground line 3273 on the metal frame 3221, as compared with the electronic device 3100 illustrated in FIG. 3D. The electronic device 3200 may be electrically connected, via the additional ground line 3273, to a ground member 3274 disposed on the board 3270.

The electronic device 3200 has the same configuration as the electronic device 3100 illustrated in FIG. 3D, except that the additional ground line 3273 and the ground member 3274 are configured. Accordingly, the remaining descriptions will be omitted.

Referring to FIGS. 4A to 4D, a folder-type electronic device 400 is shown. In FIGS. 4A and 4B, perspective views of the electronic device 400 in a folded and unfolded state, respectively, are provided. In FIG. 4C, a side view of the electronic device 400 in the folded state is provided. In FIG. 4D, a front view of the electronic device 400 in the unfolded state is provided. The electronic device 400, according to various embodiments, may be the same as electronic devices 101 and 201 of FIGS. 1 and 2 .

In FIGS. 4A to 4D, at least a portion of a housing of the electronic device 400 forms at least a portion of an antenna. For example, at least one gap may be formed in a first housing portion 410 or a second housing portion 420 of the electronic device 400.

The first housing portion 410 may be referred to as a first electronic device, and the second housing portion 420 may be referred to as a second electronic device. The electronic device 400 may further include a connection part 430. The connection part 430 may interconnect the first and second housing portions 410 and 420 to be rotatable about a rotation axis A, and may be defined as a hinge unit. For example, the hinge unit 430 may provide a pivot movement between the first and second housing portions 410 and 420. For example, the second housing portion 420 may be oriented to face the first housing portion 410, and may be folded or unfolded around the rotation axis A. The first and second housing portions 410 and 420 may form the whole or at least a portion of the exterior of the electronic device. According to various embodiments, the first and second housing portions 410 and 420 may be formed of materials, such as a plastic, a metal, carbon fiber and/or other fiber composites, ceramics, glass, and wood, or combinations thereof.

The first and second housing portions 410 and 420 may have first and second rim structures, respectively. For example, the first and second rim structures are made of a conductive material, and may be referred to as first and second conductive rim structures.

The first conductive rim structure of the first housing portion 410 may have a substantially rectangular shape that includes a first side, a second side that is shorter than the first side, a third side that has the same length as the first side, and a fourth side that has the same length as the second side.

When the electronic device 400 is in the folded state, the first and second housing portions 410 and 420 may be arranged such that the rims thereof overlap with each other in a shape where the first and second housing portions 410 and 420 are substantially aligned to each other. The first side of the first housing portion 410 may have the same length as the first side of the second housing portion 420, and the remaining sides of the first and second housing portions 410 and 420 may be equal to each other.

Each of the first and second housings 410 and 420 may have a top face, a bottom face, and a plurality of side faces. The top face, the bottom face, and the plurality of side faces of the first housing 410 may be formed of materials having the same physical property, or may be formed of materials having different physical properties. For example, the top face, the bottom face, and the plurality of side faces of the second housing 420 may be formed of the same material, or may be formed of materials having different physical properties.

The electronic device 400 may have one or more displays on each of the first housing portion 410 and the second housing portion 420. For example, the first housing portion 410 may include a first display 401 disposed on the top face thereof. The first display 401 may be a touch screen. The second housing portion 420 may include a second display 403 disposed on the top face (i.e., an outer face) thereof. The second display 403 may be a touch screen. The second housing portion 420 may include a third display 402 disposed on the bottom face (i.e., an inner face) thereof. The third display 402 may be a touch screen. The first housing portion 410 may be provided with a keyboard operated by a physical pushing operation instead of the first display 401. The one or more displays of the electronic device may be formed in different sizes. For example, the third display 403 may be configured to be smaller than the first and second displays 401 and 402, and may not be disposed.

The first housing portion 410 of the electronic device 400 may include a display 401 mounted on the top face thereof (i.e., the first display 401 may be referred to as a “touch screen” when a touch panel is mounted). The first display 401 may be formed in a large size to occupy a greater portion of the top face of the electronic device 400. The first display 401 may be the same as the display 301 illustrated in FIGS. 3A and 3B.

The first housing portion 410 of the electronic device 400 may include a first face, a second face that faces opposite to the first face, and a first side face that encloses at least a portion of the space between the first and second faces. The first housing portion 410 may include a conductive material and a non-conductive material. For example, the first housing portion 410 may have an exterior rim structure that includes a conductive member and a non-conductive member.

In the first housing portion 410, at least a portion of the front face, at least a portion of the rear face, or at least a portion of the side face may be formed of a conductive material. In the first housing portion 410, at least a portion of the front face, at least a portion of the rear face, or at least a portion of the side face may be formed of a non-conductive material. For example, in the case where the first housing portion 410 of the electronic device 400 is a metallic housing, the metallic housing may include an exterior conductive member that forms the exterior of the metallic housing. The exterior conductive member may include a metal frame arranged along the rim of the electronic device 400.

The metal member may be arranged on at least a partial region of the rim of the electronic device 400, and the remaining portion may be replaced by a non-conductive member. In such a case, the first housing portion 410 may be formed in a manner in which the non-conductive member is formed on the metal frame through insert injection molding.

The rim of the first housing portion 410 of the electronic device 400 may include a plurality of metal frames (i.e., metal portions). The metal frames may include first to fourth metal frames 411 to 414.

The metal frame positioned at the bottom side of the first housing portion 410 may be referred to as a first metal frame 411, the metal frame positioned at the top side of the first housing portion 410 may be referred to as a second metal frame 412, the metal frame positioned at the left side of the first housing portion 410 may be referred to as a third metal frame 413, and the metal frame positioned at the right side of the first housing portion 410 may be referred to as a fourth metal frame 414.

The first metal frame 411 may include one or more non-conductive members 415 and 416. Each of the non-conductive members 415 and 416 is made of a non-conductive material, and may thus be referred to as an insulation portion. Further, each of the non-conductive members 415 and 416 splits adjacent metal frames and may thus be referred to as a split portion. For example, one or more non-conductive members may be aligned along the conductive member or the side face of the housing portion. The non-conductive member may include a non-metallic portion.

The non-conductive members 415 and 416 may include a metallic material. The conductive member may include a metallic material. The metallic material may include any one of aluminum, stainless steel, and amorphous metal alloy.

The amorphous metal alloy may have a fine structure similar to a liquid phase in which no crystal structure exists because atoms are irregularly arranged, unlike a conventional alloy. Because the amorphous metal alloy has a homogeneous isotropic characteristic, and does not have a crystallographic anisotropy, the amorphous metal alloy may be excellent in mechanical strength, and because the amorphous metal alloy is uniform in structure and composition, the amorphous metal alloy has excellent corrosion resistance.

Each of the metal frames, which are split by respective non-conductive members 415 and 416 may be used as an antenna radiator. The first metal frame 411 may be a top center radiator that is provided by a pair of the non-conductive members 415 and 416 formed at a predetermined interval. For example, the non-conductive members 415 and 416 may be formed when a non-conductive member is formed on the first metal frame 411 through insert injection molding.

When the first metal frame 411 is fed with power to operate as an antenna radiator, at least a portion of each of the third and fourth metal frames 413 and 414 may be electrically coupled to the first metal frame 411 to operate as at least a portion of an antenna radiator. The third and fourth metal frames 413 and 414 may be arranged in the form of being split by a non-conductive material.

The non-conductive members 415 and 416 may be formed by filling a gap between the metal frames with a non-conductive material.

The first metal frame 411 may further include top side metal frames 413 a and 414 a that respectively extend from the third and fourth metal frames 413 and 414, and are then bent. The non-conductive members 415 and 416 may be arranged between the first metal frame 411 and the top side metal frames 413 a and 414 a, respectively.

The first metal frame 411 may operate as an antenna radiator that is fed with power from a power feeding circuit so as to form resonance. When the first metal frame 411 is fed with power from the power feeding circuit to operate as an antenna radiator that forms resonance, at least a portion of the top side metal frame 413 a and the third metal frame 413 or at least a portion of the top side metal frame 414 a and the fourth metal frame 414 are electrically coupled to each other so as to operate as at least a portion of the antenna radiator.

The first housing portion 410 of the electronic device 400 may include a communication circuit and a ground unit disposed on a board therein. The configuration, in which the center metal frame is connected to a communication circuit and a ground unit to operate as an antenna radiator that forms resonance, was described above with reference to FIG. 3C, and thus, duplicate descriptions will be omitted.

The second housing portion 420 may include a second display 402 on the bottom face thereof (i.e., the display 402 may be referred to as a “touch screen” when a touch panel is mounted). The second display 402 may be formed in a large size to occupy a greater portion of the bottom face of the electronic device 400. The second housing portion 420 may include a third display 403 on the top face thereof (i.e., the display 403 may be referred to as a “touch screen” when a touch panel is mounted).

The second housing portion 420 of the electronic device 400 may include a first face, a second face that faces opposite to the first face, and a first side face that encloses at least a portion of the space between the first and second faces. The second housing portion 420 may include a conductive material and a non-conductive material.

The second housing portion 420 may be made of a conductive member (e.g., a metal housing), and at least a portion of the front face, at least a portion of the rear face, or at least a portion of the side face of the second housing portion 420 may be made of a conductive material. Alternatively, the second housing portion 420 may be made of a non-conductive member (e.g., a non-conductive housing), and at least a portion of the front face, at least a portion of the rear face, or at least a portion of the side face of the second housing portion 420 may be made of a non-conductive material. For example, in the case where the second housing portion 420 of the electronic device 400 is a metallic housing, the metallic housing may include an exterior conductive member that forms the exterior of the metallic housing. The exterior conductive member may include a metal frame arranged along the rim of the electronic device 400.

The rim of the second housing portion 420 of the electronic device 400 may include a plurality of metal frames. The metal frames may include first to fourth metal frames 421 to 424.

The metal frame positioned at the bottom side of the second housing portion 420 may be referred to as a first metal frame 421, the metal frame positioned at the top side of the second housing portion 420 may be referred to as a second metal frame 422, the metal frame positioned at the left side of the second housing portion 420 may be referred to as a third metal frame 423, and the metal frame positioned at the right side of the second housing portion 420 may be referred to as a fourth metal frame 424.

When the electronic device 400 is in the folded state as shown in FIG. 4A, an electric field, which is generated from the first metal frame (i.e., a conductive member) 411 disposed in the first housing portion 410 and is formed in a region adjacent to the non-conductive members (i.e., insulation portions) 415 and 416, may be formed in a region other than the direction of the second housing portion 420, which may cause the antenna radiating performance to be deteriorated. For example, when the direction of an electric field is restricted to some extent, the radiation performance of the antenna is poor. Accordingly, when the electronic device 400 is of a folder-type and a non-conductive member is disposed only in the first housing portion, the antenna radiation performance may be deteriorated when the electronic device 400 is in a standby state (i.e., a folded state).

FIGS. 5A and 5B illustrate a folder-type electronic device, according to an embodiment of the present disclosure.

Referring to FIGS. 5A and 5B, a folder-type electronic device 500 is shown. In FIGS. 5A and 5B, perspective views of the electronic device 500 in a folded and unfolded state, respectively, are provided. The electronic device 500, according to various embodiments, may be the same as the electronic device 101 of FIG. 1 .

In FIGS. 5A and 5B, at least a portion of a housing of the electronic device 500 forms at least a portion of an antenna. For example, at least one gap may be formed in a first housing portion 510 or a second housing portion 520 of the electronic device 500.

The electronic device 500 according to various embodiments is different from the electronic device illustrated in FIGS. 4A to 4D only in the configuration of the second housing portion 520. The configurations of the remaining components (i.e., the first housing portion 510 and a connection part 530 are the same as those of the electronic device illustrated in FIGS. 4A to 4D). Thus, descriptions of the first housing portion 510 and the connection part 530 will be omitted. The second housing portion 520 of the electronic device 500 may include a second display 502 on the inner face thereof (i.e., the second display 502 may be referred to as a “touch screen” when a touch panel is mounted). For example, the second display 502 may be formed in a large size to occupy a greater portion of the inner face of the electronic device 500. The second housing portion 520 of the electronic device 500 may include a third display 503 mounted on the outer face thereof (i.e., the third display 503 may be referred to as a “touch screen” when a touch panel is mounted). The third display 503 may be formed to occupy a portion of the outer face of the electronic device 500.

The second housing portion 520 of the electronic device 500 may include a first face, a second face that faces opposite to the first face, and a first side face that encloses at least a portion of the space between the first and second faces. The second housing portion 520 may include a conductive material and/or a non-conductive material.

The second housing portion 520 may be made of a conductive member (e.g., a metal housing), and at least a portion of the front face, at least a portion of the rear face, or at least a portion of the side face of the second housing portion 520 may be made of a conductive material. The second housing portion 520 may be made of a non-conductive member (e.g., a non-conductive housing), and at least a portion of the front face, at least a portion of the rear face, or at least a portion of the side face of the second housing portion 520 may be made of a non-conductive material. For example, in the case where the second housing portion 520 of the electronic device 500 is a metallic housing, the metallic housing may include an exterior conductive member that forms the exterior of the metallic housing. The exterior conductive member may include at least one metal frame arranged along the rim of the electronic device 500. The metal member may be arranged only on at least a partial region of the rim of the electronic device 500, and the remaining portion may be replaced by a non-conductive member. In such a case, the second housing portion 520 may be formed in a manner in which the non-conductive member is formed on the metal frame through insert injection molding.

The rim of the second housing portion 520 of the electronic device 500 may include one or more metal frames. The metal frames may include first to fourth metal frames 521 to 524.

The metal frame positioned at the bottom side of the second housing portion 520 may be referred to as a first metal frame 521, the metal frame positioned at the top side of the second housing portion 520 may be referred to as a second metal frame 522, the metal frame positioned at the left side of the second housing portion 520 may be referred to as a third metal frame 523, and the metal frame positioned at the right side of the second housing portion 520 may be referred to as a fourth metal frame 524.

The first metal frame 521 may include one or more non-conductive members 525 and 526. Each of the non-conductive members 525 and 526 is made of an insulation material, and may thus be referred to as an insulation portion. Further, each of the non-conductive members 525 and 526 splits adjacent metal frames and may thus be referred to as a split portion.

Each of the metal frames, which are split by respective non-conductive members 525 and 526, may be used as an antenna radiator. The first metal frame 521 may be a top center frame that is provided by a pair of the non-conductive members 525 and 526 formed at a predetermined interval. For example, the non-conductive members 525 and 526 may be formed when a non-conductive member is formed on the first metal frame 521 through insert injection molding.

When the first metal frame 521 is fed with power by a power feeding circuit to operate as an antenna radiator, at least a portion of each of the third and fourth metal frames 523 and 524 may be electrically coupled to the first metal frame 521 to operate as at least a portion of an antenna radiator. The third and fourth metal frames 523 and 524 may be arranged in the form of being split by a non-conductive material (not illustrated).

The non-conductive members 525 and 526 may be formed by filling a gap (i.e., an opening) between the metal frames with a non-conductive material.

The first metal frame 521 may further include top side metal frames 523 a and 524 a that respectively extend from the third and fourth metal frames 523 and 524, and are then bent. The first non-conductive members 525 and 526 may be arranged between the first metal frame 521 and the top side metal frames 523 a and 524 a, respectively. The first metal frame 521 may operate as an antenna radiator that is fed with power from a power feeding circuit so as to form resonance. When the first metal frame 521 is fed with power from the power feeding circuit to operate as an antenna radiator, at least a portion of the top side metal frame 523 a and the third metal frame 523 or at least a portion of the top side metal frame 524 a and the fourth metal frame 524 is electrically coupled to each other so as to operate as a portion of the antenna radiator.

The second housing portion 520 of the electronic device 500 may include therein a communication circuit and a ground unit disposed on a board. The configuration, in which the first metal frame 521 is connected to a communication circuit and a ground unit to operate as at least a portion of an antenna radiator that forms resonance, was described above with reference to FIG. 3C, therefore, duplicate descriptions will be omitted.

An antenna using the metal frames of the electronic device 500 according to various embodiments is a call transmission/reception antenna, and may be any one of a CDMA antenna, a personal communication service (PCS) antenna, and a GSM antenna. However, the present disclosure is not limited thereto.

As another example, an antenna using the metal frame of the electronic device 500 may be variously used as long as it is an antenna that transmits/receives electromagnetic waves wirelessly like a GPS antenna, a Bluetooth antenna, or a wireless LAN antenna.

The electronic device 500 may differently adjust the length of an antenna depending on a bandwidth to be supported. For example, the antenna bandwidth may be differently adjusted depending on the positions of a non-conductive member, a power feeding unit, and a ground unit.

In the electronic device 500, the first non-conductive members 515 and 516 and the second non-conductive members 525 and 526 may be arranged to be substantially symmetrically aligned to each other when viewed with reference to the YZ plane. For example, the first non-conductive members 515 and 516 and the second non-conductive members 525 and 526 may be substantially aligned in the vertical direction with reference to the Z axis.

The conductive member (i.e., a center metal frame) 511 of the first housing portion 510 and the conductive member (i.e., a center metal frame) 521 of the second housing 520 may be arranged along the Z axis to be symmetric to each other.

With this arrangement, the electronic device 500 may maintain the radiation effect of the antenna even in the state where the first housing portion 510 and the second housing portion 520 are disposed close to each other (i.e., when the electronic device 500 is in a folded state).

For example, when the second housing portion 520 is disposed close to the first housing portion 510 (i.e. when the first and second non-conductive members are symmetrically aligned), radiation radiated from the antenna radiator formed by at least a portion of the first housing portion 510 may be radiated through the second non-conductive member (i.e., opening) of the second housing portion 520.

When the first face of the first housing portion 510 and the first face of the second housing portion 520 of the electronic device 500 face each other, the first non-conductive members 515 and 516 and the second non-conductive members 525 and 526 are substantially aligned so that antenna radiation may be executed through the open region of the antenna formed in the first housing portion 510 and an open region of the second housing portion 520 substantially aligned thereto. Thus, when the antenna radiation is executed to the open region of the second housing 520, the deterioration of the antenna radiation performance can be prevented.

FIGS. 6A and 6B illustrate a distribution of electric fields generated from at an electronic device, according to an embodiment of the present disclosure.

Referring to FIGS. 6A and 6B, an electronic device 600 is shown. The electronic device 600, according to various embodiments, may be the same as the electronic device 101 of FIG. 1 .

The electronic device 600 includes first non-conductive members 615 and 616 of a first housing portion 610. Many electric fields may be formed in the vicinity of the first non-conductive members 615 and 616.

A second housing portion 620 may include second non-conductive members 625 and 626, which are located at the positions corresponding to the first non-conductive members 615 and 616. A passage may be formed, through which the electric fields generated in the vicinity of the first non-conductive members 615 and 616 may be radiated toward the second housing portion 620, so that many electric fields may also be formed in the vicinity of the second non-conductive members 625 and 626.

The electric fields may be generated in a shape that encompasses the whole of the first housing portion 610 and the second housing portion 620. As shown in FIGS. 6A and 6B, many electric fields are also formed toward the second housing portion 620.

The electronic device 600 may be provided with second non-conductive members 625 and 626 in the second housing portion 620 so as to maintain the radiation direction of the energy fields generated from the first non-conductive members 615 and 616, and the first conductive member 611 and the second conductive member 621, which are centrally positioned, may be electrically coupled to each other so as to maintain a better radiation performance.

FIG. 7 is a graph representing radiation efficiencies of an electronic device in various frequency bands, according to an embodiment of the present disclosure.

Referring to FIG. 7 the graph illustrates radiation efficiencies for various frequency bands (low band, mid band, and high band) in a case where a non-conductive member exists in a second housing portion 520 of the electronic device 500 and a case where a non-conductive member does not exist in the second housing portion 520 of the electronic device 500. That is, the graph illustrates a case where first split portions (e.g., the positions, each of which has an opening shape, and where the first non-conductive members 515 and 516 are located) are disposed in the first housing portion 510, and second split portions (e.g., the positions, each of which has an opening shape, and where the second non-conductive members 525 and 526 aligned with the first non-conductive members are located) exist (e.g., the electronic device 500 in the folded state, as in FIG. 5A), and in a case where first split portions (e.g., the positions, each of which has an opening shape, and where the first non-conductive members 515 and 516 are located), and second split portions (e.g., the positions, each of which has an opening shape, and where the second non-conductive members 525 and 526 aligned with the first non-conductive members are located) do not exist (e.g., the electronic device 400 in the folded state, as in FIG. 4A). The low band may be in the range of about 800 MHz to 1000 MHz, the mid band may be in the range of about 1700 MHz to 2200 MHz, and the high band may be in the range of 2300 MHz to 2700 MHz.

As shown in FIG. 7 , the antenna employed in the electronic device 500 exhibits a higher total radiation efficiency for respective frequency bands in the case where the split portions corresponding to the first split portions exist in the second housing portion 520 (the upper curve in the graph) (e.g., the electronic device in the folded state as in FIG. 5A) as compared to that in the case where the second split portions do not exist in the second housing portion 520 (the lower curve in the graph) (e.g., the electronic device in the folded state as in FIG. 4A).

Table 1, shows a comparison of the radiation efficiency for respective frequency bands when the second split portions (e.g., the non-conductive members 525 and 526) corresponding to the first split portions (e.g., the first non-conductive members 515 and 516) of the first housing portion 510 exist in the second housing portion 520 and the radiation efficiency in the case where the second split portions do not exist in the second housing portion 520.

TABLE 1 Band (MHz) 850 900 1800 1900 2100 2^(nd) Split portion 2.75% 6.97% 9.91% 14.6% 12.8% does not exist (−15.6 dB) (−11.6 dB) (−10 dB) (−8.36 dB) (−8.93 dB) 2^(nd) Split portion 20.4% 22.7% 24.1% 27.4% 20.3% exists (−6.9 dB) (−6.44 dB) (−6.19 dB) (−5.63 dB) (−6.93 dB) Difference 8.7 dB 5.16 dB 3.81 dB 2.73 dB 2 dB

Referring to Table 1, the antenna employed in the electronic device, according to various embodiments, may be greatly improved in radiation performance when the second split portions exist in the second housing portion 520, as compared to the case where no second split portion exists.

Referring to Table 1, various embodiments exhibit a great difference in radiation performance in the low band (850 to 900 MHz). In the low band (850 to 900 MHz), it can be seen that the radiation efficiency is improved three or more times in the level of 5.16 dB to 8.7 dB.

For example, in the 850 MHz band, which is the low band, the radiation efficiency in the case where no second split portion exists in the second housing portion 520 (e.g., the electronic device in the folded state as in FIG. 4A) is 14.6% while the radiation efficiency in the case where the second split portions exist in the second housing portion 520 (e.g., the electronic device in the folded state as in FIG. 5A) is improved to 20.4%.

According to another example, in the 900 MHz band, which is the low band, the radiation efficiency in the case where no second split portion exists in the second housing portion 520 (e.g., the electronic device in the folded state as in FIG. 4A) is 6.97% while the radiation efficiency in the case where the second split portions exist in the second housing portion 520 (e.g., the electronic device in the folded state as in FIG. 5A) is improved to 22.7%.

In the 1900 MHz band, which is the mid band, the radiation efficiency in the case where no second split portion exists in the second housing portion 520 (e.g., the electronic device in the folded state as in FIG. 4A) is 2.75% while the radiation efficiency in the case where the second split portions exist in the second housing portion 520 (e.g., the electronic device in the folded state as in FIG. 5A) is improved to 27.4%.

In addition, in the 2000 MHz band, which is the mid band, the radiation efficiency in the case where no second split portion exists in the second housing portion 520 (the electronic device in the folded state as in FIG. 4A) is 12.8% while the radiation efficiency in the case where the second split portions exist in the second housing portion 520 (the electronic device in the folded state as in FIG. 5A) is improved to 20.3%.

In addition, in the 2500 MHz band, which is the high band, the radiation efficiency can be improved in the case where the second split portions exist in the second housing portion 520 (e.g., the electronic device in the folded state as in FIG. 5A) as compared to the case where no second split portion exists in the second housing portion 520 (the electronic device in the folded state as in FIG. 4A).

FIG. 8 illustrates a folder-type electronic device, according to an embodiment of the present disclosure.

Referring to FIG. 8 , a perspective view of a folder-type electronic device 800 in a folded state is shown. The electronic device 800, according to various embodiments, may be the same as the electronic device 101 of FIG. 1 .

In FIG. 8 , at least one gap may be formed in a first housing portion 810 and/or a second housing portion 820 of the electronic device 800.

The first and second housing portions 810 and 820 of the electronic device 800 may be rotatably connected to each other by a connection part 830. According to various embodiments, each of the first and second housing portions 810 and 820 may include a conductive member and/or a non-conductive member. For example, in the electronic device 800, the first and second housing portions 810 and 820 may include one or more metal frames 811 and 821 disposed along the rims thereof, respectively.

The electronic device 800 may include at least one non-conductive member that is formed in a region adjacent to the connection part 830 that interconnects the first housing portion 810 and the second housing portion 820. For example, the electronic device 800 may include first non-conductive members 815 and 816 and second non-conductive members 825 and 826, which may be respectively disposed in the first and second metal frames 811 and 821 of the first and second housing portions 810 and 820 in which the connection part 830 is disposed.

Each of the first and second metal frames 811 and 821, which are split by each of the first non-conductive members 815 and 816 and the second non-conductive members 825 and 826, may be used as an antenna radiator. The first non-conductive members 815 and 816 and the second non-conductive members 825 and 826 may be formed by filling gaps (i.e., openings) between the first and second metal frames with a non-conductive material.

In the folded/unfolded state of the electronic device 800, the first non-conductive members 815 and 816 and the second non-conductive members 825 and 826 may be respectively disposed in the first metal frame 811 and the second metal frame 821 positioned around the connection part 830. The first non-conductive members 815 and 816 and the second non-conductive members 825 and 826 may be disposed at the opposite sides of the connection part 830, respectively.

The connection part 830 may be referred to as a hinge unit because it provides a rotation axis of the first and second housing portions 810 and 820. The connection part 830 may include at least one hinge arm, and a hinge cam, a hinge shaft, a hinge spring, and so on, which are known in the art, may be disposed inside the hinge arm.

The first non-conductive members 815 and 816 and the second non-conductive members 825 and 826 may be aligned to each other, and the first and second metal frames 811 and 821 may be aligned to each other. For example, the first non-conductive members 815 and 816 and the second non-conductive members 825 and 826 may be arranged to be vertically symmetric to each other with reference to the connection part 830, and the first metal frame 811 and the second metal frame 812 may be arranged to be vertically symmetric to each other with reference to the connection part 830.

When the first face of the first housing portion 810 and the first face of the second housing portion 820 of the electronic device 800 face each other, the first non-conductive members 815 and 816 and the second non-conductive members 825 and 826 are substantially aligned so that antenna radiation may be executed through the open region of the antenna formed in the first housing portion 810 and an open region of the second housing portion 820 substantially aligned thereto. Thus, when the antenna radiation is executed to the open region of the second housing 820, deterioration of the antenna radiation performance can be prevented.

The electronic device 800 is not limited to an arrangement in which the first non-conductive members 815 and 816 and the second non-conductive members 825 and 826 are disposed around the connection part 830. Instead, each of the first non-conductive members 815 and 816 and the second non-conductive members 825 and 826 may be disposed in a symmetric or asymmetric arrangement on the metal frames disposed in at least the remaining portion, other than a portion where the connection part 830 is disposed, in each of the first and second housing portions 810 and 820.

FIGS. 9A and 9B illustrate a folder-type electronic device, according to an embodiment of the present disclosure.

Referring to FIGS. 9A and 9B, a folder-type electronic device 900 is shown. In FIGS. 9A and 9B, perspective views of the electronic device 900 in a folded and unfolded state, respectively, are provided. The electronic device 900, according to various embodiments, may be the same as the electronic device 101 of FIG. 1 .

In FIGS. 9A and 9B, at least a portion of a housing of the electronic device 900 forms at least a portion of an antenna. For example, at least one gap may be formed in a first housing portion 910 and/or a second housing portion 920 of the electronic device 900.

The electronic device 900 may include one or more non-conductive members, which are disposed on the first housing portion 910 and the second housing portion 920, respectively. Non-conductive members may be arranged in the first housing portion 910 and the second housing portion 920, respectively, such that the number of non-conductive members in the first housing portion 910 may be different from the number of non-conductive members in the second housing portion 920. Non-conductive members may be asymmetrically arranged in the first housing portion 910 and the second housing portion 920, respectively, and the number of non-conductive members arranged in the first housing portion 910 may be different from the number of non-conductive members arranged in the second housing portion 920.

For example, first non-conductive members 915 and 916 may be disposed in the first housing portion 910 and a second non-conductive member 925 may be disposed in the second housing portion 920. One non-conductive member 915 disposed in the first housing portion 910 and the second non-conductive member 925 disposed in the second housing portion 920 may be arranged to be aligned to each other. The non-conductive members disposed in the electronic device 900 may be arranged not only in the regions of the first and second metal frames 911 and 921 of the first and second housing portions 910 and 920, but also in the second metal frames 912 and 922, the third metal frames 913 and 923, or the fourth metal frames 914 and 924 of the first and second housing portions as the same arrangement structures.

The electronic device 900 is different from the electronic device illustrated in FIGS. 4A to 4D only in the configuration of the second housing portion 920. The configurations of the remaining components (i.e., the first housing portion 910 and a connection part 930 are the same as those of the electronic device illustrated in FIGS. 4A to 4D). Thus, descriptions of the first housing portion 910 and the connection part 930 will be omitted.

The rim of the second housing portion 920 of the electronic device 900 may include a plurality of metal frames (i.e., conductive portions). The metal frames may include first to fourth metal frames 921 to 924 depending on the disposed positions thereof.

The first housing portion 910 and the second housing portion 920 of the electronic device 900 may include non-conductive members, in which the number of the non-conductive members disposed in the first housing portion 910 may be different from the number of the non-conductive members disposed in the second housing portion 920. For example, the first metal frame 921 of the second housing portion 920 may include the second non-conductive member 925. Each of the metal frames 921 and 923, which are split by the first non-conductive member 925, may be used as at least a portion of an antenna radiator. The second non-conductive member 925 may be disposed at a side of the first metal frame 921. For example, in the state illustrated in FIG. 9A, the first non-conductive members 915 and 916, and the second non-conductive member 925 may be arranged asymmetrically in the vertical direction and in the horizontal direction. For example, in the state where the first and second housing portions 910 and 920 of the electronic device are folded, the non-conductive member 915 of the first housing portion and the second non-conductive member 925 of the second housing portion may be arranged to be superimposed one on another, which may improve an antenna radiation efficiency.

The second non-conductive member 925 may be formed by filling a gap (i.e., an opening) between the metal frames 921 and 923 with a non-conductive material.

The electronic device 900 may differently adjust the length of an antenna depending on a bandwidth to support. For example, the antenna bandwidth may be differently adjusted depending on the positions of a non-conductive member (i.e., the opening or gap), a power feeding unit, and a ground unit.

When the first face of the first housing portion 910 and the first face of the second housing portion 920 of the electronic device 900 face each other, the non-conductive member 915 and the second non-conductive member 925 are substantially aligned so that antenna radiation may be executed through the open region of the antenna formed in the first housing portion 910 and an open region of the second housing portion 920 substantially aligned thereto. Thus, when the antenna radiation is executed to the open region of the second housing 920, the deterioration of the antenna radiation performance can be prevented.

FIGS. 10A and 10B illustrate a folder-type electronic device, according to an embodiment of the present disclosure.

Referring to FIGS. 10A and 10B, a folder-type electronic device 1000 is shown. In FIGS. 10A and 10B, perspective views of the electronic device 1000 in a folded and unfolded state, respectively, are provided. The electronic device 1000, according to various embodiments, may be the same as the electronic device 101 of FIG. 1 .

In FIGS. 10A and 10B, at least a portion of a housing of the electronic device 1000 forms at least a portion of an antenna. For example, at least one gap may be formed in a first housing portion 1010 or a second housing portion 1020 of the electronic device 1000.

The electronic device 1000 may include one or more non-conductive members, which are disposed on the first housing portion 1010 and the second housing portion 1020, respectively.

Non-conductive members may be arranged in the first housing portion 1010 and the second housing portion 1020, respectively, and the number of non-conductive members arranged in the first housing portion 1010 may be different from the number of non-conductive members arranged in the second housing portion 1020. Non-conductive members may be asymmetrically arranged in the first housing portion 1010 and the second housing portion 1020, respectively, and the number of non-conductive members arranged in the first housing portion 1010 may be different from the number of non-conductive members arranged in the second housing portion 1020.

For example, a first non-conductive member 1015 may be disposed in the first housing portion 1010 and two or more second non-conductive members 1025 and 1026 may be disposed in the second housing portion 1020. The first non-conductive member 1015 disposed in the first housing portion 1010 and one second non-conductive member 1025 disposed in the second housing portion 1020 may be arranged to be aligned to each other.

The non-conductive members disposed in the electronic device 1000 may be arranged not only in the regions of the first and second metal frames 1011 and 1021 of the first and second housing portions 1010 and 1020, but also in the second metal frames 1012 and 1022, the third metal frames 1013 and 1023, or the fourth metal frames 1014 and 1024 of the first and second housing portions as the same arrangement structures.

The electronic device 1000 is different from the electronic device illustrated in FIGS. 4A to 4D only in the configuration of the first housing portion 1010. The configurations of the remaining components (i.e., the second housing portion 1020 and a connection part 1030 are the same as those of the electronic device illustrated in FIGS. 4A to 4D). Thus, descriptions of the second housing portion 1020 and the connection part 1030 will be omitted. The rim of the first housing portion 1010 of the electronic device 1000 may include a plurality of metal frames (i.e., conductive portions). The metal frames may include first to fourth metal frames 1011 to 1014 depending on the disposed positions thereof.

The first metal frame 1011 may include the first non-conductive member 1015. Each of the metal frames 1011 and 1013, which are split by the first non-conductive member 1015, may be used as an antenna radiator. The first non-conductive member 1015 may be disposed at a side of the first metal frame 1011. For example, in the state illustrated in FIG. 10A, the first non-conductive members 1015, and the second non-conductive members 1025 and 1026 may be arranged asymmetrically in the vertical direction and in the horizontal direction. In the state where the first and second housing portions 1010 and 1020 of the electronic device 1000 are folded, the first non-conductive member 1015 of the first housing portion and the second non-conductive member 1025 of the second housing portion may be arranged to be superimposed one on another, which may improve an antenna radiation efficiency.

The first non-conductive member 1015 may be formed by filling a gap (i.e., an opening) between the metal frames 1011 and 1013 with a non-conductive material.

The electronic device 1000 may differently adjust the length of an antenna depending on a bandwidth to support. For example, the antenna bandwidth may be differently adjusted depending on the positions of a split portion (i.e., the opening or gap), a non-conductive member, a power feeding unit, and a ground unit.

When the first face of the first housing portion 1010 and the first face of the second housing portion 1020 of the electronic device 1000 face each other, the first non-conductive member 1015 and the second non-conductive member 1025 are substantially aligned so that antenna radiation may be executed through the open region of the antenna formed in the first housing portion 1010 and an open region of the second housing portion 1020 substantially aligned thereto. Thus, when the antenna radiation is executed to the open region of the second housing 1020, the deterioration of the antenna radiation performance can be prevented.

FIGS. 11A and 11B illustrate a folder-type electronic device, according to an embodiment of the present disclosure.

Referring to FIGS. 11A and 11B, a folder-type electronic device 1100 is shown. In FIGS. 11A and 11B, perspective views of the electronic device 1100 in a folded and unfolded state, respectively, are provided. The electronic device 1100, according to various embodiments, may be the same as the electronic device 101 of FIG. 1 .

In FIGS. 11A and 11B, at least a portion of a housing of the electronic device 1100 forms at least a portion of an antenna. For example, at least one gap may be formed in a first housing portion 1110 and/or a second housing portion 1120 of the electronic device 1100.

The electronic device 1100 may include one non-conductive member, which is disposed in each of the first housing portion 1110 and the second housing portion 1120. Non-conductive members may be arranged in the first housing portion 1110 and the second housing portion 1120, respectively, and the number of non-conductive members arranged in the first housing portion 1110 may be the same as the number of non-conductive members arranged in the second housing portion 1120. Non-conductive members may be symmetrically arranged in the first housing portion 1110 and the second housing portion 1120, respectively, and the number of non-conductive members arranged in the first housing portion 1110 may be the same as the number of non-conductive members arranged in the second housing portion 1120.

For example, a first non-conductive member 1115 may be disposed in the first housing portion 1110 and a second non-conductive member 1125 may be disposed in the second housing portion 1120. The first non-conductive member 1115 disposed in the first housing portion 1110 and the second non-conductive member 1125 disposed in the second housing portion 1120 may be arranged to be aligned to each other.

The non-conductive members disposed in the electronic device 1100 may be arranged not only in the regions of the first and second metal frames 1111 and 1121 of the first and second housing portions 1110 and 1120, but also in the second metal frames 1112 and 1122, the third metal frames 1113 and 1123, or the fourth metal frames 1114 and 1124 of the first and second housing portions as the same arrangement structures.

The electronic device 1100 may further include a connection part 1130. The configuration of both the first and second housing portions 1110 and 1120 is the same as that of the first housing portion 910 illustrated in FIGS. 9A and 9B, and thus, detailed descriptions thereof will be omitted. The first metal frame 1111 of the first housing portion may include a single non-conductive member 1115. Each of the metal frames 1111 and 1113, which are split by the single non-conductive member 1115, may be used as an antenna radiator. The first non-conductive member 1115 may be disposed at a side of the first metal frame 1111. The first metal frame 1121 of the second housing portion may include a single non-conductive member 1125. Each of the metal frames 1121 and 1123, which are split by the second non-conductive member 1125, may be used as an antenna radiator. The second non-conductive member 1125 may be disposed at a side of the first metal frame 1121.

When the first face of the first housing portion 1110 and the first face of the second housing portion 1120 of the electronic device 1100 face each other, the first non-conductive member 1115 and the second non-conductive member 1125 are substantially aligned so that antenna radiation may be executed through the open region of the antenna formed in the first housing portion 1110 and an open region of the second housing portion 1120 substantially aligned thereto. Thus, when the antenna radiation is executed to the open region of the second housing 1120, the deterioration of the antenna radiation performance can be prevented.

In the state illustrated in FIG. 11A, the first and second non-conductive members 1115 and 1125 may be arranged symmetrically in the vertical direction and symmetrically in the horizontal direction. In the state where the first and second housing portions 1110 and 1120 are folded, each of the first and second non-conductive members 1115 and 1125 may be disposed to be superimposed one on another, which may improve an antenna radiation efficiency.

FIGS. 12A and 12B illustrate a folder-type electronic device, according to an embodiment of the present disclosure.

Referring to FIGS. 12A and 12B, a folder-type electronic device 1200 is shown. In FIGS. 12A and 12B, perspective views of the electronic device 1200 in a folded and unfolded state, respectively, are provided. The electronic device 1200, according to various embodiments, may be the same as the electronic device 101 of FIG. 1 .

In FIGS. 12A and 12B, at least a portion of a housing of the electronic device 1200 forms at least a portion of an antenna. For example, at least one gap may be formed in a first housing portion 1210 or a second housing portion 1220 of the electronic device 1200.

The electronic device 1200 may include one non-conductive member, which is disposed in each of the first housing portion 1210 and the second housing portion 1220. Non-conductive members may be arranged in the first housing portion 1210 and the second housing portion 1220, respectively, and the number of non-conductive members arranged in the first housing portion 1210 may be the same as the number of non-conductive members arranged in the second housing portion 1220. Non-conductive members may be symmetrically arranged in the first housing portion 1210 and the second housing portion 1220, respectively, and the number of non-conductive members arranged in the first housing portion 1210 may be the same as the number of non-conductive members arranged in the second housing portion 1220.

For example, two first non-conductive members 1215 and 1216 may be disposed in the first housing portion 1210 and two second non-conductive members 1225 and 1226 may be disposed in the second housing portion 1220. The two first non-conductive members 1215 and 1216 disposed in the first housing portion 1210 and the two second non-conductive members 1225 and 1226 disposed in the second housing portion 1220 may be arranged to be aligned to each other. For example, in the state where the electronic device 1200 is folded, first non-conductive members 1215 and 1216 and second non-conductive members 1225 and 1226 may be arranged on the metal frames to be symmetric in the vertical direction and in the horizontal direction.

The non-conductive members disposed in the electronic device 1200 may be arranged not only in the regions of the first and second metal frames 1211 and 1221 of the first and second housing portions 1210 and 1220, but also in the second metal frames 1212 and 1222, the third metal frames 1213 and 1223, or the fourth metal frames 1214 and 1224 of the first and second housing portions as the same arrangement structures.

The electronic device 1200 may further include a connection part 1230. The electronic device 1200 may be different from the electronic device 400 illustrated in FIGS. 4A to 4D in terms of the arrangement positions of the non-conductive members disposed in each of the first and second housing portions 1210 and 1220. The metal frames forming the rim of the first housing portion 1210 may include first to fourth metal frames 1211 to 1214. The metal frames forming the rim of the second housing portion 1220 may include first to fourth metal frames 1221 to 1224.

The fourth metal frame 1214 of the first housing 1210 may include one or more of the first non-conductive members 1215 and 1216. The first non-conductive members 1215 and 1216 may be mounted on the fourth metal frame to be symmetric to each other.

Each of the metal frames, which are split by respective first non-conductive members 1215 and 1216, may be used as an antenna radiator. The fourth metal frame may be a center metal frame that is provided by a pair of the first non-conductive members 1215 and 1216 formed at a predetermined interval. When the first metal frame 1214 is fed with power to operate as an antenna radiator, at least a portion of each of the first and second metal frames 1211 and 1212 may be electrically coupled to the fourth metal frame 1214 to operate as an antenna radiator. The first non-conductive members 1215 and 1216 may be formed by filling a gap (i.e., an opening) between the metal frames with a non-conductive material.

The fourth metal frame 1214 of the first housing portion may further include side metal frames 1211 a and 1212 a that respectively extend from the first and second metal frames 1211 and 1212 and are bent at a right angle. The first non-conductive members 1215 and 1216 may be arranged between the fourth metal frame 1214 and the side metal frames 1211 a and 1212 a, respectively. When the fourth metal frame 1214 is fed with power, the fourth metal frame 1214 may operate as an antenna radiator that is fed with power from a power feeding circuit so as to form resonance. When the fourth metal frame 1214 is fed with power from the power feeding circuit to operate as an antenna radiator, at least a portion of the side metal frame 1211 a and the first metal frame 1211 or at least a portion of the side metal frame 1212 a and the second metal frame 1212 is electrically coupled to each other so as to operate as a portion of the antenna radiator.

The fourth metal frame 1224 of the second housing portion 1220 may include one or more of the second non-conductive members 1225 and 1226. Each of the second non-conductive members 1225 and 1226 may be mounted on the fourth metal frame 1224 to be symmetric to each other.

Each of the metal frames 1224, which are split by the respective second non-conductive members 1225 and 1226, may be used as an antenna radiator. The fourth metal frame 1224 of the second housing portion may be a center frame 1224 that is provided by the second non-conductive members 1225 and 1226 formed at a predetermined interval. When the fourth metal frame 1224 of the second housing portion is fed with power by a power feeding circuit to operate as at least a portion of an antenna radiator that forms resonance, at least a portion of each of the first and second metal frames 1221 and 1222 may be electrically coupled to the center metal frame 1224 to operate as an antenna radiator. The second non-conductive members 1225 and 1226 may be formed by filling a gap (i.e., an opening) between the metal frames with a non-conductive material.

The fourth metal frame 1224 of the second housing portion may further include side metal frames 1221 a and 1222 a that respectively extend from the first and second metal frames 1211 and 1212 and are then bent at a right angle. The second non-conductive members 1225 and 1226 may be arranged between the fourth metal frame 1224 of the second housing portion and the top side metal frames 1221 a and 1222 a, respectively. When the fourth metal frame 1224 is fed with power by a power feeding circuit, the fourth metal frame 1224 may operate as an antenna radiator that forms resonance. When the fourth metal frame 1224 is fed with power from the power feeding circuit to operate as a radiator, at least a portion of the side metal frame 1221 a and the first metal frame 1221 or at least a portion of the side metal frame 1222 a and the second metal frame 1222 is electrically coupled to each other so as to operate as an antenna radiator.

In the electronic device 1200, the first non-conductive members 1215 and 1216 and the second non-conductive members 1225 and 1226 may be arranged to be substantially symmetrically aligned to each other when viewed with reference to the YZ plane. For example, the first non-conductive members 1215 and 1216 and the second non-conductive members 1225 and 1226 may be substantially aligned in the vertical direction with reference to the Z axis.

The fourth metal frame 1214 of the first housing portion 1210 and the fourth metal frame 1224 of the second housing 1220 may be aligned to be vertically symmetric to each other along the Z axis.

With this arrangement, the electronic device 1200 may maintain the radiation effect of the antenna even in the state where the first housing portion 1210 and the second housing portion 1220 are disposed close to each other (i.e., when the electronic device 1200 is in a folded state).

When the second housing portion 1220 is disposed closed to the first housing portion 1210 (i.e. when the first non-conductive members 1215 and 1216 and the second non-conductive members 1225 and 1226 are symmetrically aligned), radiation radiated from the antenna radiator formed by at least a portion of the first housing portion 1210 may be radiated through the second non-conductive member (i.e., the opening) of the second housing portion 1220.

The first non-conductive members 1215 and 1216 and the second non-conductive members 1225 and 1226 may be equally arranged on the third frames 1213 and 1223 of the first and second housing portions, respectively.

The disposed number of each of the first non-conductive members 1215 and 1216 and the second non-conductive members 1225 and 1226 does not need to be limited to two, and may be one or three or more.

When the first face of the first housing portion 1210 and the first face of the second housing portion 1220 of the electronic device 1200 face each other, the first non-conductive members 1215 and 1216 and the second non-conductive members 1225 and 1226 are substantially aligned so that antenna radiation may be executed through the open region of the antenna formed in the first housing portion 1210 and an open region of the second housing portion 1220 substantially aligned thereto. Thus, when the antenna radiation is executed to the open region of the second housing 1220, the deterioration of the antenna radiation performance can be prevented.

FIGS. 13A and 13B illustrate a folder-type electronic device, according to an embodiment of the present disclosure.

Referring to FIGS. 13A and 13B, a folder-type electronic device 1300 is shown. In FIGS. 13A and 13B, perspective views of the electronic device 1300 in a folded and unfolded state, respectively, are provided. The electronic device 1300, according to various embodiments, may be the same as the electronic device 101 of FIG. 1 .

In FIGS. 13A and 13B, at least a portion of a housing of the electronic device 1300 forms at least a portion of an antenna. For example, at least one gap may be formed in a first housing portion 1310 and/or a second housing portion 1320 of the electronic device 1300.

The electronic device 1300 may include one or more non-conductive member, which may be disposed in each of the first housing portion 1310 and the second housing portion 1320. Non-conductive members may be arranged in the first housing portion 1310 and the second housing portion 1320, respectively, and the number of non-conductive members arranged in the first housing portion 1310 may be different from the number of non-conductive members arranged in the second housing portion 1320. Non-conductive members may be symmetrically arranged in the first housing portion 1310 and the second housing portion 1320, respectively, and the number of non-conductive members arranged in the first housing portion 1310 may be different from the number of non-conductive members arranged in the second housing portion 1320.

For example, two first non-conductive members 1315 and 1316 may be disposed in the first housing portion 1310 and one second non-conductive member 1325 may be disposed in the second housing portion 1320. One non-conductive member 1315 of the first housing portion 1310 and the second non-conductive member 1325 of the second housing portion 1320 may be arranged to be substantially aligned to each other when the first housing portion 1310 and the second housing portion 1320 face each other. In the state where the electronic device 1300 is folded, first non-conductive members 1315 and 1316 and second non-conductive member 1325 may be arranged on the metal frames to be asymmetric in the vertical direction and in the horizontal direction.

The non-conductive members disposed in the electronic device 1300 may be arranged not only in the regions of the first and second metal frames 1311 and 1321 of the first and second housing portions 1310 and 1320, but also in the second metal frames 1312 and 1322, the third metal frames 1313 and 1323, or the fourth metal frames 1314 and 1324 of the first and second housing portions 1310 and 1320 as the same arrangement structures.

The electronic device 1300 is different from the electronic device 1200 illustrated in FIGS. 12A and 12B only in the configuration of the second housing portion 1320. The configurations of the remaining components, (i.e., the first housing portion 1310 and a connection part 1330 are the same as those of the electronic device 1200 illustrated in FIGS. 12A to 12B). Thus, descriptions of the first housing portion 1310 and the connection part 1330 will be omitted. The rim of the second housing portion 1320 of the electronic device 1300 may include a plurality of metal frames (i.e., conductive portions). The metal frames may include first to fourth metal frames 1321 to 1324 depending on the disposed positions thereof.

The fourth metal frame 1324 may include the second non-conductive member 1325. Each of the metal frames 1321 and 1324, which are split by the second non-conductive member 1325, may be used as an antenna radiator. The second non-conductive member 1325 may be disposed at a side of the fourth metal frame 1324. In the state illustrated in FIG. 13A, the first non-conductive members 1315 and 1316 and the second non-conductive member 1325 may be arranged asymmetrically in the vertical direction and in the horizontal direction. In the state where the first and second housing portions 1310 and 1320 are folded, the first non-conductive member 1315 and the second non-conductive member 1325 may be disposed to be superimposed one on another, which may improve an antenna radiation efficiency. The second non-conductive member 1325 may be formed by filling a gap (i.e., an opening) between the metal frames 1321 and 1324 with a non-conductive material.

The disposed number of each of the first non-conductive members 1315 and 1316 and the second non-conductive members 1326 in each of the first and second housing portions 1310 and 1320 does not need to be limited, and a plurality of non-conductive members may be variously disposed.

When the first face of the first housing portion 1310 and the first face of the second housing portion 1320 of the electronic device 1300 face each other, the first non-conductive member 1315 and the second non-conductive member 1325 are substantially aligned so that antenna radiation may be executed through the open region of the antenna formed in the first housing portion 1310 and an open region of the second housing portion 1320 substantially aligned thereto. Thus, when the antenna radiation is executed to the open region of the second housing 1320, the deterioration of the antenna radiation performance can be prevented.

FIGS. 14A and 14B illustrate a folder-type electronic device, according to an embodiment of the present disclosure.

Referring to FIGS. 14A and 14B, a folder-type electronic device 1400 is shown. In FIGS. 14A and 14B, perspective views of the electronic device 1400 in a folded and unfolded state, respectively, are provided. The electronic device 1400, according to various embodiments, may be the same as the electronic device 101 of FIG. 1 .

In FIGS. 14A and 14B, at least a portion of a housing of the electronic device 1400 forms at least a portion of an antenna. For example, at least one gap may be formed in a first housing portion 1410 and/or a second housing portion 1420 of the electronic device 1400.

The electronic device 1400 may include one or more non-conductive members, which are disposed on the first housing portion 1410 and the second housing portion 1420, respectively. Non-conductive members may be arranged in the first housing portion 1410 and the second housing portion 1420, respectively, and the number of non-conductive members arranged in the first housing portion 1410 may be different from the number of non-conductive members arranged in the second housing portion 1420. Non-conductive members may be asymmetrically arranged in the first housing portion 1410 and the second housing portion 1420, respectively, and the number of non-conductive members arranged in the first housing portion 1410 may be different from the number of non-conductive members arranged in the second housing portion 1420.

For example, one first non-conductive member 1415 may be disposed in the first housing portion 1410 and two second non-conductive members 1425 and 1426 may be disposed in the second housing portion 1420. The first non-conductive member 1415 disposed in the first housing portion 1410 and one first non-conductive member 1425 disposed in the second housing portion 1420 may be arranged to be aligned to each other.

The non-conductive members disposed in the electronic device 1400 may be arranged not only in the regions of the first and second metal frames 1411 and 1421 of the first and second housing portions 1410 and 1420, but also in the second metal frames 1412 and 1422, the third metal frames 1413 and 1423, or the fourth metal frames 1414 and 1424 of the first and second housing portions 1410 and 1420 as the same arrangement structures.

The electronic device 1400 is different from the electronic device illustrated in FIGS. 12A and 12B only in the configuration of the first housing portion 1410. The configurations of the remaining components (i.e., the second housing portion 1420 and a connection part 1430 are the same as those of the electronic device 1200 illustrated in FIGS. 12A and 12B). Thus, descriptions of the second housing portion 1420 and the connection part 1430 will be omitted. The rim of the first housing portion 1410 of the electronic device 1400 may include a plurality of metal frames (i.e., conductive portions). The metal frames may include first to fourth metal frames 1411 to 1414 depending on the disposed positions thereof.

The fourth metal frame 1414 may include the first non-conductive member 1415. Each of the metal frames 1411 and 1414, which are split by the first non-conductive member 1415, may be used as an antenna radiator. The first non-conductive member 1415 may be disposed at a side of the fourth metal frame 1414. In the state illustrated in FIG. 14A, the first non-conductive member 1415 and the second non-conductive members 1425 and 1426 may be arranged asymmetrically in the vertical direction and in the horizontal direction. In the state where the first and second housing portions 1410 and 1420 are folded, the first non-conductive member 1415 and the one second non-conductive member 1425 may be disposed to be superimposed one on another, which may improve an antenna radiation efficiency.

When the first face of the first housing portion 1410 and the first face of the second housing portion 1420 of the electronic device 1400 face each other, the first non-conductive member 1415 and the one second non-conductive member 1425 are substantially aligned so that antenna radiation may be executed through the open region of the antenna formed in the first housing portion 1410 and an open region of the second housing portion 1420 substantially aligned thereto. Thus, when the antenna radiation is executed to the open region of the second housing 1420, the deterioration of the antenna radiation performance can be prevented.

Each of the first and second non-conductive members 1415, 1425, and 1426 may be equally arranged the third frames 1413 and 1423 of the first and second housing portions, respectively.

FIGS. 15A and 15B illustrate a folder-type electronic device, according to an embodiment of the present disclosure.

Referring to FIGS. 15A and 15B, a folder-type electronic device 1500 is shown.

The electronic device 1500 may include one non-conductive member, which is disposed in each of the first housing portion 1510 and the second housing portion 1520. Non-conductive members may be arranged in the first housing portion 1510 and the second housing portion 1520, respectively, and the number of non-conductive members arranged in the first housing portion 1510 may be the same as the number of non-conductive members arranged in the second housing portion 1520. Non-conductive members may be symmetrically arranged in the first housing portion 1510 and the second housing portion 1520, respectively, and the number of non-conductive members arranged in the first housing portion 1510 may be the same as the number of non-conductive members arranged in the second housing portion 1520.

For example, one first non-conductive member 1515 may be disposed in the first housing portion 1510 and one second non-conductive member 1525 may be disposed in the second housing portion 1520. The first non-conductive member 1515 disposed in the first housing portion 1510 and second non-conductive member 1525 disposed in the second housing portion 1520 may be arranged to be aligned to each other.

The non-conductive members disposed in the electronic device 1500 may be arranged not only in the regions of the first and second metal frames 1511 and 1521 of the first and second housing portions 1510 and 1520, but also in the second metal frames 1512 and 1522, the third metal frames 1513 and 1523, or the fourth metal frames 1514 and 1524 of the first and second housing portions 1510 and 1520 as the same arrangement structures.

The configuration of both the first and second housing portions 1510 and 1520 of the electronic device 1500 is the same as that of the first housing portion 1410 illustrated in FIGS. 14A and 14B, and thus, detailed descriptions thereof will be omitted. The first metal frame 1511 of the first housing portion may include the first non-conductive member 1515. Each of the metal frames 1511 and 1512, which are split by the first non-conductive member 1515, may be used as an antenna radiator. The first non-conductive member 1515 of the first housing portion may be disposed at a side of the first metal frame 1511. The first metal frame 1521 of the second housing portion may include the second non-conductive member 1525.

The second non-conductive member 1525 may be disposed at a side of the first metal frame 1521.

In the state illustrated in FIG. 15A, the first and second non-conductive members 1515 and 1525 may be arranged symmetrically in the vertical direction and asymmetrically in the horizontal direction. In the state where the first and second housing portions 1510 and 1520 are folded, each of the first and second non-conductive members 1515 and 1525 may be disposed to be superimposed one on another, which may improve an antenna radiation efficiency.

When the first face of the first housing portion 1510 and the first face of the second housing portion 1520 of the electronic device 1500 face each other, the first non-conductive member 1515 and the second non-conductive member 1525 are substantially aligned so that antenna radiation may be executed through the open region of the antenna formed in the first housing portion 1510 and an open region of the second housing portion 1520 substantially aligned thereto. Thus, when the antenna radiation is executed to the open region of the second housing 1520, the deterioration of the antenna radiation performance can be prevented.

In the electronic device 1600, the configurations of the first non-conductive members 1615 a and 1616 a and the second non-conductive members 1625 a and 1626 a, which are respectively disposed in the first metal frames 1611 and 1621 of the first and second housing portions 1610 and 1620, are the same as those of the first non-conductive members 515 and 516 and second non-conductive members 525 and 526, which are respectively disposed in the first metal frames 511 and 521 of the first and second housing portions 510 and 520 that have been described with reference to FIGS. 5A and 5B, and thus detailed descriptions thereof will be omitted. In the electronic device 1600, the configurations of the first non-conductive members 1615 b and 1616 b and second non-conductive members 1625 b, and 1626 b, which are respectively disposed in the fourth metal frames 1614 and 1624 of the first and second housing portions 1610 and 1620, are the same as those of the first non-conductive members 1215 and 1216 and second non-conductive members 1225 and 1226, which are respectively disposed in the fourth metal frames 1214 and 1224 of the first and second housings 1210 and 1220 that have been described with reference to FIGS. 12A and 12B, and thus detailed descriptions thereof will be omitted.

In the electronic device 1600, the first non-conductive members 1615 a and 1616 a of the first housing portion and the second non-conductive members 1625 a and 1626 a of the second housing portion may be arranged to be substantially symmetrically aligned to each other when viewed with reference to the YZ plane. For example, in the electronic device 1600, the first non-conductive members 1615 a and 1616 a of the first housing portion and the second non-conductive members 1625 a and 1626 a of the second housing portion may be arranged to be substantially aligned to each other in the vertical direction and in the horizontal direction with reference to the Z axis.

According to various embodiments, when the first face of the first housing portion 1610 and the first face of the second housing portion 1620 of the electronic device 1600 face each other, the first non-conductive members 1615 a, 1616 a and the second non-conductive members 1625 a and 1626 a and the first non-conductive members 1615 b and 1616 b and the second non-conductive members 1625 b and 1626 b are substantially aligned so that antenna radiation may be executed through the open region of the antenna formed in the first housing portion 1610 and an open region of the second housing portion 1620 substantially aligned thereto. Thus, when the antenna radiation is executed to the open region of the second housing 1620, the deterioration of the antenna radiation performance can be prevented.

With this arrangement, the electronic device 1600 may maintain the radiation effect of the antenna even in the state where the first housing portion 1610 and the second housing portion 1620 are disposed close to each other (i.e., when the electronic device 1600 is in a folded state).

FIG. 17 illustrates a folder-type electronic device, according to an embodiment of the present disclosure.

Referring to FIG. 17 , a perspective view of a folder-type electronic device 1700 in the folded state is shown. The electronic device 1700, according to various embodiments, may be the same as the electronic device 101 of FIG. 1 .

For example, at least one gap may be formed in a first housing portion 1710 and/or a second housing portion 1720 of the electronic device 1700. The electronic device 1700 is provided with a connection part 1730 so as to fold or unfold the first and second housing portions 1710 and 1720, in which the connection part 1730 may be disposed along the vertical side (Y axis) of the first and second housing portions 1710 and 1720.

The electronic device 1700 may include one or more non-conductive member, which may be disposed in each of the first housing portion 1710 and the second housing portion 1720. Non-conductive members may be arranged in the first housing portion 1710 and the second housing portion 1720, respectively, and the number of non-conductive members arranged in the first housing portion 1710 may be the same as the number of non-conductive members arranged in the second housing portion 1720. Non-conductive members may be symmetrically arranged in the first housing portion 1710 and the second housing portion 1720, respectively, and the number of non-conductive members arranged in the first housing portion 1710 may be the same as the number of non-conductive members arranged in the second housing portion 1720.

For example, in the state where the electronic device 1700 is folded, two first non-conductive members 1715 and 1716 may be disposed in the first housing portion 1710 and two second non-conductive members 1725 and 1726 may be disposed in the second housing portion 1720. The first non-conductive members 1715 and 1716 disposed in the first housing portion 1710 and the second non-conductive members 1725 and 1726 disposed in the second housing portion 1720 may be arranged to be aligned to each other. For example, in the state where the electronic device 1700 is folded, first non-conductive members 1715 and 1716 and second non-conductive members 1725 and 1726 may be arranged on the metal frames to be symmetric in the vertical direction and in the horizontal direction.

In the electronic device 1700, the first non-conductive members 1715 and 1716 and the second non-conductive members 1725 and 1726 may be arranged to be substantially symmetrically aligned to each other when viewed with reference to the XZ plane. For example, the first non-conductive members 1715 and 1716 and the second non-conductive members 1725 and 1726 may be substantially aligned in the vertical direction and in the horizontal direction with reference to the Z axis.

With this arrangement, the electronic device 1700 may improve the radiation efficiency of the antenna even in the state where the first housing portion 1710 and the second housing portion 1720 are disposed close to each other (i.e., when the electronic device 1700 is in a folded state). When the first face of the first housing portion 1710 and the first face of the second housing portion 1720 of the electronic device 1700 face each other, the first non-conductive members 1715 and 1716 and the second non-conductive members 1725 and 1726 are substantially aligned so that antenna radiation may be executed through the open region of the antenna formed in the first housing portion 1710 and an open region of the second housing portion 1720 substantially aligned thereto. Thus, when the antenna radiation is executed to the open region of the second housing 1720, the deterioration of the antenna radiation performance can be prevented.

FIG. 18 illustrates a folder-type electronic device, according to an embodiment of the present disclosure.

Referring to FIG. 18 , a perspective view of a folder-type electronic device 1800 in the folded state is shown. The electronic device 1800, according to various embodiments, may be the same as the electronic device 101 of FIG. 1 .

In FIG. 18 , at least a portion of a housing of the electronic device 1800 forms at least a portion of an antenna. For example, at least one gap may be formed in a first housing portion 1810 and/or a second housing portion 1820 of the electronic device 1800.

The electronic device 1800 may include one or more non-conductive members, which are disposed on the first housing portion 1810 and the second housing portion 1820, respectively. Non-conductive members may be arranged in the first housing portion 1810 and the second housing portion 1820, respectively, and the number of non-conductive members arranged in the first housing portion 1810 may be different from the number of non-conductive members arranged in the second housing portion 1820. Non-conductive members may be asymmetrically arranged in the first housing portion 1810 and the second housing portion 1820, respectively, and the number of non-conductive members arranged in the first housing portion 1810 may be different from the number of non-conductive members arranged in the second housing portion 1820.

For example, at least two first non-conductive members 1815 and 1816 may be disposed in the first housing portion 1810 and one second non-conductive member 1825 may be disposed in the second housing portion 1820. One first non-conductive member 1815 disposed in the first housing portion 1810 and the second non-conductive member 1825 disposed in the second housing portion 1820 may be arranged to be aligned to each other.

For example, the non-conductive members disposed in the electronic device 1800 may be arranged not only in the regions of the first and second metal frames 1811 and 1821 of the first and second housing portions 1810 and 1820, but also in the second metal frames 1812 and 1822 of the first and second housing portions, the third metal frame 1823 of the first and second housing portions, or the fourth metal frame 1824 of the first and second housing portions as the same arrangement structures.

The electronic device 1800 may further include a connection part 1830. The connection part 1830 may be disposed along the vertical direction (Y axis) of the first and second housing portions 1810 and 1820.

In the electronic device 1800, the first non-conductive members 1815 and 1816 of the first housing portion and the second non-conductive member 1825 of the second housing portion may be arranged to be substantially asymmetrically aligned to each other when viewed with reference to the XZ plane. For example, the first non-conductive members 1815 and 1816 and the second non-conductive member 1825 may be arranged substantially asymmetrically in the vertical direction and in the horizontal direction.

When the first face of the first housing portion 1810 and the first face of the second housing portion 1820 of the electronic device 1800 face each other, the one first non-conductive member 1815 and the second non-conductive member 1825 are substantially aligned so that antenna radiation may be executed through the open region of the antenna formed in the first housing portion 1810 and an open region of the second housing portion 1820 substantially aligned thereto. Thus, when the antenna radiation is executed to the open region of the second housing 1820, the deterioration of the antenna radiation performance can be prevented.

In the state where the first and second housing portions 1810 and 1820 are folded, each of the non-conductive members 1815 and 1825 may be disposed to be superimposed one on another, which may improve an antenna radiation efficiency.

FIG. 19 illustrates a folder-type electronic device, according to an embodiment of the present disclosure.

Referring to FIG. 19 , a perspective view of a folder-type electronic device 1900 in the folded state is shown. The electronic device 1900, according to various embodiments, may be the same as the electronic device 101 of FIG. 1 .

In the electronic device 1900, the second non-conductive members 1925 and 1926 and the first non-conductive member 1915 may be arranged to be substantially asymmetrically aligned to each other when viewed with reference to the XZ plane. For example, the first non-conductive member 1915 and the second non-conductive members 1925 and 1926 may be arranged substantially asymmetrically in the vertical direction and in the horizontal direction.

When the first face of the first housing portion 1910 and the first face of the second housing portion 1920 of the electronic device 1900 face each other, the first non-conductive member 1915 and the one second non-conductive member 1925 are substantially aligned so that antenna radiation may be executed through the open region of the antenna formed in the first housing portion 1910 and an open region of the second housing portion 1920 substantially aligned thereto. Thus, when the antenna radiation is executed to the open region of the second housing 1920, the deterioration of the antenna radiation performance can be prevented.

In the state where the first and second housing portions 1910 and 1920 are folded, each of the non-conductive members 1915 and 1925 may be disposed to be superimposed one on another, which may improve an antenna radiation efficiency.
